  • Where are you trying to push? GitHub? GitLab? Bitbucket? Somewhere else? – ChrisGPT was on strike Apr 08 '18 at 18:28
  • GitHub .......... – moro clash Apr 08 '18 at 18:36
  • Not sure how long are you using Git & Github, but I am using it for a very long time and from yesterday I am having exactly the same error. – edelmaks Apr 09 '18 at 18:57
  • I use it for a very long time too, and I never see this error before...... Git was work fine.... but this error happened suddenly, and it happened with other people with different os's – moro clash Apr 09 '18 at 21:27

    Ok in windows it was the outdated Git Credential Manager problem. Updated from [here](https://github.com/Microsoft/Git-Credential-Manager-for-Windows/releases/) and the error is gone. Probably there is one for Linux as well. – edelmaks Apr 13 '18 at 14:26

So I ran into the same issue and contacted github.com/contact. In the end, they gave the hint that solved it for me. I needed to change the git config to use TLSv1.2 instead of SSLv3:

git config http.sslVersion tlsv1.2

As GitHub support told me, in the beginning, the issue could be related to a change which they deployed a few months ago, that disables support for deprecated legacy TLS and SSH algorithms, including those that were used in older versions of some Git clients.

  • Although it didn't help me with exactly the same error, there is a tip if you get `warning: unsupported ssl version TLSv1.2: using default` - type `tlsv1.2` in lowercase. – edelmaks Apr 11 '18 at 23:07

    git config --global http.sslVersion tlsv1.2 to set it globally. – sudip Dec 21 '21 at 21:53
  • This worked after upgrading Git to version `2.37.3`. It didn't work before I did. – GMaiolo Sep 13 '22 at 17:54
  • If you're not currently in a repo, you'll likely need to add the `--global` flag after `git config` or you'll get an error – Aaron Meese Aug 20 '23 at 15:07

This is the final answer:

git config --global http.postBuffer 1048576000

I had a similar issue and solved it by updating Git.
If you're on Windows run Command Prompt as Administrator and execute

git update-git-for-windows

in my case, these commands work

1. git config http.postBuffer 524288000

2. git push

if git push is not working then use this one

1. git push origin branch-name
